Orgalutran is a hormonal drug used in assisted reproduction treatments. Its active ingredient is ganirelix, an antagonist of the GnRH hormone secreted by the hypothalamus. Orgalutran acts by blocking the woman's menstrual cycle, so that spontaneous ovulation is prevented from occurring during fertility treatment.
